A intake part before and after cleaning :)

I can share delicat's experience with this system so far. No difference at all (except of some money missing in my wallet). I didn't assume a race car after the installation, but at least a "yeah, I feel something". We read the installation manual back and forth, checked your forum, measured the exhaust temperature with the system on and off. I actually mixed my own mix (50/50, Methanol/Water) with the calculator from your forum. We also experimented with the regulator. Tried it in all settings from 2 till 10psi. Now we ran out of ideas or is the difference just nothing you can feel while driving with your food down? Maybe we installed it wrong? I hope at least the engine gets cleaner and there is an increase of mileage.

Is the fluid level in the tank going down? Did you prime the pump prior to installing the hose into the nozzle holder? The pump cannot clear air past the check valve. To make sure everything is hooked up correctly all you need to do is turn the key to ignition on and move the one wire on the pressure switch from NO to NC to run the pump. (that's with the hose not in the nozzle holder so all the air is out of the system.

Hey,
Definetly interested in more power (of course!),
but also very interested in the whole engine cleaning aspect of it!
In terms of offsetting any build-up from running WVO and mixes therof
(old motor oil,tranny fluid, half finished beers and red bulls... )

Thank You guys for trying this out it seems like something
positive will come of it!

Right on!

Hey there.
I just put in a pre/turbo 1gph nozzle.felt a slight difference.I then put in a 2gph after turbo instead of the 1gph.Felt increase in power,exhaust temp stayed the same.With the 2gph i have noticed more engine noise,rattle.Sort of sounds like my 3/4 ton dodge.Is this normal?
I am using washer fluid -40c.When I used 50/50 meth. water mix,my exhaust temp went up to 1200F after turbo.
When I was first using the 1gph after turbo only,no pre/turbo,I felt no increase in power.It took about 4 weeks then more power came out.Also my oil stayes cleaner longer.
I have my switch to turn on at 13psi,power is from 3600-4200 rpm.
Max boost is 14.5 psi.I have also advanced my injection timing by 1mm on then bottom mounting flange.

Guamdoc, I guess you didn't read my post on p.10 explaining what was done... But I just went back and purged it again, this time right at the nozzle like you suggested and it's pouring which means the system should be working. I'm going for a ride right now, if I don't see any difference than we'll "chat" again...

Your sounds like to much alcohol in your mix, If you don't see a drop in EGT's at all it means your at the edge the water can offset the methanol. That knocking sound is like when you run to much propane injection in a diesel You need to always start out low like 20% don't go right for a 50/50 mix.

If you use the 1gph pre-turbo with the 2gph nozzle it will be a much larger difference in power plus you'll pick up RPM's must faster due to the fact the turbo will spool up quicker. Which you probably notice that already,

Sorry did not see page 10 until just now. Also one more thing, the line you have your pressure switch connected to would you use the same line for your boost gauge? Just making sure it's a good activation spot even though you guys most likely hooked it up in the same spot just got to check to rule it out.

One of the reasons we carry the level switch is so you will know your low on fluid so if you have hooked up a toggle switch you can simply turn it off.

If you run the system dry the pump will just run, it can run for hours and hours in the dry state, it will not hurt anything but your going to have to purge the system of air again. The purge process is different for the dual nozzle system it's not at the nozzle holder because the check valve is not part of the assembly there. Always purge right before the check valve then give it a quick squirt with the whole system hooked up.

Guamdoc;
Get's confusing at the end! If purging is done both at nozzles and check valve, any reason we don't notice any difference? (and yes, vacuum comes from the boost line).

So, to notice any gains (power, lower EGT, cleaner intake)...
Do we need to advance our timing? (and probably add more fuel, either via your system or via IP)
Do we need to increase boost?

Big question, why don't we see any gains if your system is properly installed?

Thanks,

Every vehicle is different but you should at least notice some gains just like the other member, The kit allows you to increase boost, timing, and fueling safely. You also might have a boost leak or some other un-realated issue like a slipping transmission that is not allowing the transfer of power. But if that is a non-issue then it sounds simply like nozzle size. I am taking it you have two 1gph nozzle in the set up. Like the other rig that is noticing the power gains with the 2gph nozzle means you also need a bit more nozzle. Most of the pre-turbo nozzle is used up cooling the turbo so it really does not count towards flow. You can also try running 20% alcohol only and see if you get a EGT drop, water does a much better job than alcohol.

To save you the pain of putting both in the intake and plugging the hole I'll just hook you up with a D02 nozzle to add on. I know Mont who is running this on his Pajero is up to a 3gph nozzle on the intake and 1gph pre-turbo with no problems, He actually dynoed 4hp higher than the last time with that set up.

PM me your address and I'll have the shop shoot you a couple of sizes to play with. If someone has a DO2 left over from the install then that's even better. Cars are like people what works well on one may not work as well on another you just got to change the dosage sort to speak. Also as your internals get a steam cleaning you notice a much smoother engine and a bit more power, this is pretty common place just like other member mentions.

Thanks Guamdoc,

The rig that noticed improvements ended up advancing his timing and increasing his boost, that should explain his gains. I was just under the impression that we'd notice something without altering the base engine settings.

And I understand the need to fine tune this system, just wanted to have your input as to the best way to do it...

Thanks again.
D.

one way to test to see if it is doing it's job, do a pull up the cut in N.Van, or up Gaglardi with the water/meth off, log your egt's, then give it a shot after with it on? shouldn't turn into the usual deli-slug as easily.

it would interesting to see Garyo's results with the IC and water/meth.

Well for 99.9% of the dyno's of the 4cly turbo diesels I have posted on here we have done zero to them they are bone stock just like the Pajero 4D56 dyno. There are so many little factors that can effect performance from boost leaks, to bad trannys to injector pumps not up to snuff. That's why we use the dyno if were going to prove results.

You have some nozzle headed your way today, via priority mail so should be there in less than a week. You can feel free to distributive the extras.

Oh yes, altitude also plays a huge role in the gains, most of ours are done at sea level.

I am no longer using 50/50 mix,egt way too high.I am just using straight washer fluid.Do I need to dilute the washer fluid with water?
I now need to find a different location for my tank.Mount broke again,tank hit a/c compression,big hole.So no injection for now.
Just wanted to make sure you understood my set up.1gph pre/turbo 2gph after turbo,2gph not too large?
